Cabin crew members have an important duty of keeping passengers happy during short or long-haul flights.

Not only do they satisfy customers by serving food and drink, some can help to soothe frayed nerves.

Passengers who struggle with flying can be eased by sitting with their family and friends.

But if your seat numbers aren’t together, flight attendants don’t like being asked to move other passengers.

According to Sarah Steeger, a cabin crew member, this is one question passengers should avoid asking.

She told The Sun: “I know it's no fun to travel separated, but I have no real authority to make people move – unless talking about special need passengers like young children, the elderly or passengers with disabilities.

"If you're asking me [to move people for you], it means you saw that the seat map was full, didn't try [to swap seats at] the gate (where it should be handled) and/or the agents have already said they couldn't do anything.

"If it was easy it would have been done already, right? Agents often pass this back to us, and we simply have nowhere else to pass it.

"I have little power here, but you're standing there looking so unhappy that it's hard to say no."

Meanwhile, another flight attendant revealed why passengers should never ask about delays.

This is because the cabin crew staff can’t control how long delays last.

The worker told Business Insider: “Don’t ask me if the plane’s going to be late because of the delay, because I don’t know.”
